Our troop allowed use of axel locations extended out on the body. The wheels were trued & polished on a mandrel and the axels polished on a drill press. Std graphite lubrication. Those slots in the body are often not true and many kids cars self destruct over several runs with axels falling out of the slots.
Axel holes made with drill press so they were dead on. Some weight is far back in the car... car still has to track straight to be fast... more stored kinetic energy since the start is on an incline... cars with more weight in the rear 1/2 of the car accelerate past other cars as they hit the flat part of the track.
The unlimited class will be a kick... I've still got plenty of other unmentioned tricks in my tank.
Some plug shops will turn into speed shops the 2 wks before the "Derby"
